When accelerating with a controller ("wheel") the throttle sticks in the game at the highest input position until you return the accelerator to 0 position. I thought initially this didn't happen in 'A' gear, but it also does.
Using Win 10 64 bit. Thrustmaster Warthog controller with TARGET software (meaning it wont matter which controller, most likely will only work on a few or none).
So basically the throttle is like it has cruise control + button on at all times (for a real car).
There is a similar report, but no response on if the bug is noted, scheduled , or anything.
